Most paperweight canes are solid, but I have come across the expression "hollow canes" some years ago to describe, presumably, blown canes. Can anybody shed any light on this. In particular, in the eighties I was told that Bacarat used hollow canes and this made their weights more special.

RAY:
it's something to do with putting canes into a hollow tube, reheating them and the glass blower suck's the air out, but i could be wrong

KevinH:
I've not heard about this myself, but I will ask around.

Frank:
I think it is just a clear glass centre to a cane. Which lots of paperweight makers used.

RAY:
just found some info on hollows cane process here and its a good read
